Background: The electrocardiogram (ECG) is the most important procedure to examine the cardiac rhythm and conduction system abnormalities. The common problem of ECG misinterpretation can lead to inappropriate diagnoses and clinical decisions. There is a limited number of studies identifying the size of the problem in Saudi Arabia. We aimed to assess the frequency of ECG misreading, address the nature of errors, and analyze the determinants of ECG interpretation accuracy among sixth-year medical students and interns of Taif University, Taif, Saudi Arabia.Methods: Participants were given a quiz of 10 multiple-choice questions of commonly encountered ECG interpretations. Each correct answer was given a 1-point score. The overall score for each participant was calculated out of 10 points.Results: A total of 297 participants took part in this study and achieved a median (IQR) overall score of 6.0 (4). The most frequent score was 9 (13.5%), followed by 8 (12.8%) and 4 (12.5%). Second degree AV block, type II was misread by 60.6% of the participants, 2nd-degree AV block, type I was misread by 50.2% while other abnormalities were less frequently misread. Academic year and gender showed no significant influence on ECG interpretation. On the other hand, interest in ECG reading and previous participation in ECG courses were associated with significantly better performance (p<0.001 and p=0.001, respectively).Conclusions: Overall performance of medical students and interns was moderate. Self-learning and providing organized educational courses on ECG can positively improve ECG interpretation and allow adequate diagnosis and management of heart diseases.

Background: Neonatal jaundice occurs worldwide and contributes significantly to neonatal morbidity and mortality. Recently, newborns are being discharged early from hospitals, so parents have the primary responsibility for early recognition, appropriate response and seeking proper treatment. Objectives: To assess parents' knowledge, attitude and practice towards NNJ in different regions in Saudi Arabia. Methods: This is a crosssectional study involving 4413 expectant parents during July-September 2017 had been performed. A selfadministered questionnaire was created to obtain respondents information. Descriptive statistics were used to describe the answers of participants in the study. Comparing the answers to different questions within different groups was done using Pearson chi-square test. Statistical significance was set at p =< 0.01 and analysis was performed using IBM SPSS statistics, version 23 (IBM, Armonk, NY, USA). Results: Out of 4413 participants, females were (79.4%) while (20.6%) were males. Participants were from all regions of Saudi Arabia, with the highest percentage from central region (29.5%), most of them lived in cities (89.6%). Age group 20-30 years constituted (46.6%), and age above 50 years was 4.5% (p= <0.01). Most of the participants had a university level of education (76.6%). Relatives and friends were the main sources of knowledge for (52.6%) of the participants, followed by treating doctor in (29.8%). In (34%) of the participants' knowledge was gained after their child had NNJ, while in (42.1%) while their child was free of NNJ. Warning signs knowledge depended on the level of education and occupation where university graduates and health care workers were most knowledgeable and the difference was significant (p=<0.01). Awareness about necessity and effectiveness of treatment were dependent on older age, occupation, and place of residence (p=<0.01). Hospital treatment was done only by (23.4%), believing that it wasn't a serious disease in (18.1%) of participants, while (5%) believed that it needed no treatment at all. Conclusion: Knowledge, attitude, and practice of parents in our study, depended on age, level of education, occupation, and place of residence might have contributed to the delayed appropriate management of severe hyperbilirubinemia. We recommend the engagement of health professionals in educational settings like seminars, workshops and periodical counseling sessions to provide appropriate knowledge to parents.
